  • circumferential grooves dividing the surfaces of the channels into multiple parts and sinking beneath these surfaces are formed on the drums.
  • the transport drum comprises a plurality of discs whereas circumferential grooves between adjacent discs are formed, the borders of the discs do not contact one another, and for transporting the rods the concavities formed in the discs are used so that together they form channels for the rods.
  • the surfaces of the channels get dirty with both the dust and the particles of cut material.
  • the accumulation of dirt within the grooves may result in disturbances in the operation of the unit, which is why there is a need for a solution enabling cleaning of these grooves, but the abovementioned documents have not revealed any methods of drum cleaning.
  • the subject matter of the invention is a cleaning system for a drum conveyor of an apparatus for feeding filter segments in the tobacco industry
  • a transport drum comprises a plurality of discs on the circumferential surface of which concavities are formed whereas the concavities of respective discs are positioned relative to one another so that together they form channels receiving the filter rods, in the said channels the filter rods are transported during cutting whereas the borders of adjacent discs do not contact each other and in this way they form circumferential grooves.
  • the cleaning system is characterized in that the discs have passages discharging the dirt, circumferential grooves have a connection with the passages discharging the dirt, and the system comprises a vacuum channel receiving the dirt having a connection with the passages discharging the dirt in the discs.
  • a system according to the invention is characterized in that it comprises cleaning means inserted into circumferential grooves for tearing off the dirt from the walls of the circumferential grooves.
  • a system according to the invention is characterised in that the cleaning means are designed as movable and deflect if they encounter pieces of dirt which have strongly adhered to the groove walls.
  • a system according to the invention is characterised by comprising a cleaning means position sensor and a control system which switches off the unit in which the cleaning system is installed if the position sensor signals a deflection of the cleaning means.
  • the subject matter of the invention is also a method of cleaning a drum conveyor of an apparatus for feeding filter segments in the tobacco industry
  • the drum consists of a plurality of discs on the circumferential surface of which concavities are formed whereas the concavities of respective discs are positioned to one another so that together they form channels receiving the filter rods, in the said channels the filter rods are transported during cutting whereas the borders of adjacent discs do not contact each other and in this way they form circumferential grooves.
  • a method according to the invention is characterized in that the dirt being formed during rod cutting is discharged by vacuum to circumferential grooves, and next the dirt is discharged by vacuum to passages made in the discs, and then the dirt is discharged by vacuum to channels receiving the dirt.
  • a method according to the invention is characterized in that the dirt which has adhered to the walls of circumferential grooves is mechanically removed by means of movable cleaning means inserted into the circumferential grooves.
  • a method according to the invention is characterized in that the position of movable cleaning means is controlled and the unit in which the cleaning system is installed is switched off if the position sensor signals a deflection of the cleaning means.
  • the use of the cleaning system allows very effective cleaning of the drum from the dust and the particles of material of cut filter rods because they are received when tearing off and just after tearing them off the surface of the grooves of the drum.
  • a plurality of channels disposed on the drum allows a uniform cleaning of the drum during the operation.
  • FIG. 1 shows a fragment of a filter segment feeding apparatus during the operation of the apparatus
  • FIG. 2 shows a fragment of a filter segment feeding apparatus after stopping the operation
  • FIG. 3 shows a cross-section A-A of FIG. 1 through a channel for receiving the rods and a channel discharging the dirt

  • FIG. 1 shows a fragment of a filter segment feeding apparatus.
  • the filter rods 1 which during the operation of the apparatus are cut into filter segments are accumulated in a hopper 2 .
  • a rotatable transport drum 3 comprising a plurality of discs 4 is situated which have concavities 5 formed on their circumferential surfaces.
  • the concavities are positioned relative to one another so that together they form channels 6 receiving the filter rods 1 .
  • a cutting head 7 provided with circular knives 8 used for cutting the filter rods 1 into segments during the transport of the filter rods 1 on the transport drum 3 .
  • the circular knives 8 are situated in relation to the transport drum 3 so that their cutting edges sink into circumferential grooves 9 formed between the borders of individual discs 4 ( FIG. 3 ).
  • the cleaning means 10 e.g., a plurality of cleaning plates 10 ) the position of which is controlled by a sensor 11 is also inserted into these grooves. For reasons of simplification, the drive systems of the drum and the cutting head have not been shown.
  • FIG. 3 shows a cross-section through a receiving channel 6 on a transport drum 3 marked in FIG. 1 as A-A.
  • the discs 4 adjacent to one another, forming the transport drum 3 adjoin one another outside of the border, where they do not contact one another, and in this way the circumferential grooves 9 are formed.
  • Each of the discs 4 has a plurality of passages 12 discharging the dirt made in the border area of the discs 4 whereas the passages are disposed in such a way that they cross the circumferential grooves 9 .
  • the passages 12 discharging the dirt made in the successive discs 4 are situated relative to one another so that they form a channel 13 discharging the dirt.

  • dust from the filter material of the rods is formed, in addition, particles of this material may tear off.
  • the circumferential grooves 9 situated directly opposite the circular knives 8 have a connection with a plurality of channels 13 discharging the dirt.
  • successive discharging channels 13 with their outlet passage 16 move next to the inlet passage 14 to the vacuum channel 15 receiving the dirt.
  • the dirt from the discharging channel 13 is transferred by vacuum to the receiving channel 15 whereas the dirt is transferred further to a not shown dirt container, e.g. in the form of a dust filter.
  • the disclosed cleaning system according to the invention enables effective discharging of dirt forming in the course of cutting the filter rods from the transport drum 3 .
  • movable cleaning means 10 which is inserted into the circumferential grooves 9 , is used.
  • the particles of the filter material torn off by the cleaning means 10 will also be removed by vacuum and transferred to the channel 15 receiving the dirt.
  • the movable cleaning means is deflected or otherwise moved away, which has been shown in FIG. 2 , in particular it concerns particles which can be soiled with glue or other substances contained in the filter or the paper wrapping the filter rod causing the adherence to the walls.
  • a change of position of the cleaning means 10 will be detected by a sensor 11 which will send a signal to the control system in order to switch off the unit or the entire apparatus.
  • FIG. 4 shows a cross-section through a channel 6 receiving the filter rods 1 without the cleaning means 10 marked as B-B in FIG. 2 .
  • Both the dust and the material particles being formed during cutting when passing in the direction of an outlet passage 16 of a discharging channel 13 and before an inlet passage 14 of a receiving channel 15 , are subjected to a difference in pressure between a pressure inside the receiving channel 15 occurring for example at the point X and a pressure within the receiving channel 6 occurring for example at the points Y.
  • the difference in pressure causes an airflow shown in the diagrammatic form by a thick line.
  • the airflow shown occurs during the removal of dirt from the circumferential grooves 9 by the cleaning means 10 as well as just after the removal of dirt, which ensures high efficiency of the cleaning system.
